# Which of the following is used for insulation of electricity carrying wires and cables?

$\begin{array}{1 1}(a)\;\text{Alcohol}&(b)\; \text{High density polythene}\\(c)\;\text{Ethylene}&(d)\;\text{Low density polythene}\end{array}$

Low density polythene (LDP) is transparent of moderate tensile strength and high toughners.It is chemically inert.They are used for insulation of electricity carrying wires and cables.
Hence (d) is the correct answer.
